Be it known that 1, ROBERT J. Orin, a citizen of the United States, anda resident of lYoodhaven, in the borough and county of Queens, city and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a. specification. j

This invention relates to writing machines, and particularly to machines for writing tion Serial Number 255,326, which has become Patent Number'1,391,788 issued Sept. 2?, 1921, in which a writing sheet-upon which the music characters and signs are to be impressed is carried by a platen to have to and fro longitudinal movement with a platen carriage with the necessary mechanism to advance the carriage with the platen step by stepv letter space distances in the usuahinanner of typewriting ma- 7 chines, and in which means are provided to line spacdthe platen at will either forwardly or backwardly distances representative of one or more degrees, or multiples-thereof,

of a music staff; 1

It is: the object of the present invention to provide an improved paper shelf or ta is to "extend longitudinally of and "abovethe writing line of the platen with means to hold the paper or writing sheet firmly in contact with such shelf to facilitate the man braces and slurs or lines representative of ex ression, as crescendo, diminuendo, etc.

t is a further object of the invention to provide a templet for use in connection with the paper shelf for the manual writing of lines of expression, such as slurs or the like, or other. music signs, in connection with I mechanically written characters.

In the drawing accompanying and forming a part of this specification, Figure 1 is a plan View of my inproved paper table or shelf, showing the same mounted upon a platen frame in relation to the platen.

Figure2 is a cross sectional view showing the relation of the paper shelf or table to the platen.

Figure 3 is an enlarged side elevation, partly in section, of the'paper holding and musical notations, the present application. being a division of my oo-pend ng applica chines.

connection with;

Similar characters of reference designate like parts throughout the different .views of the drawing. An embodiment of the invention is shownin the drawing in connection with a cylin drical platen 17 0f a type-writing machine fixed to an axle 17 wherebythe :platen is; rotatably mounted in-the ends 18 ofa platen frame to have to and fro movement in line spacing direction by knobs 19 secured to the ends of the platen axle, type carried by type bars (not shown) being adapted to strike, rearwardly against the front of the platen as is common in front strike writing-ma The paper or writing sheet, shown in a general way at P (Figure 2) to receive. the impressions upon the platen is guided be tween feed rollers'21 and' theplaten and around the platen byta table 22 extending between the ends of the platen, and the platen is releasabl'yretained in' pr edetermined writing position by a yielding detent 28 co-operating with one or both of toothed wheels 20. .7 As stated it is an object of the present in' vention'to provide means to facilitate the manual writing of" music signs in connection with mechanically written characters of music notation and for this purpose, a paper shelf or table 24 is provided to extend along and above theplaten, said shelfins;

clining downward and forward toward-the rialwiththe side edges bent up at right ana.

gles to provide guide ledges 25 for the side edges of the paper. The longitudinal edge of the'shelf is curled downwardly or curved, as at 26, to engage over studs 27 carried by brackets 28-secured to and projecting up platen.

Wardly' from the platen frame ends, said studs extending inwardly parallel with t By so mounting the shelf it is adapted to be adjustedto throw the leading edge thereof into or out of engagement with the platen, To maintain the writing sheet in contact and flat against the shelf as it is fed by the platen and feed rollers 21 rollers 29, shown two in number, are provided to engage with the top of the paper shelf. These rollers 29 are carried by resilient arms or fingers 3O mountedon a .rod 31 extending longitudinally above the shelf and rotatably supported at .itsends in the shelfledges 25.

To; maintain these fingers in position on the rod to'yieldingly urge the rollers 29 against the paper shelf, the rod has a flattened por tion 32 with which the free ends of both.

spring'm'enibers 33 .(Figures 5, 6 and '7) carried by the fingers is adaptedto normally engage. By this arrangement the fingers may be r otatedo'n the rod independently of each other to throw either one or both of the.

rollersinto'or out of engagement with the paper shelf, and'to adjust the fingers along the rod.

rangedwit'h clips 3 l-adapted to engage in openings 35 (Figure l) in the fingers 30 and may-be bent over as shown at 36 (Figure 3) to secure them to said fingers.

Toth'row both of th'e fingers simultaneously out of'or into engagement with the paper shelf a finger lever 37 is secured to one end of the rod outside of a shelf ledge 25, this-finger leverbeing made of resilient niate'rialto operate as a detent to retain the rod and-fingers in position with the rollers in or out of engagement with the paper shelf. For this pu-rpose'the finger lever has a protuberance 38 extending laterally thereof'toward the shelf ledge and'when the roll e'rs are in engagement with the paper shelf engagesin a perforation in the shelf ledge, and when the rod is ad usted to position wlththe fingers held in position with the rollers out of engagement with the paper shel-f said protuberance engages with the top of the shelf ledge. To prevent throwing the'roller carrying fingers too far back an ear 39 is'bent laterally from the shelf ledge to serve as a stop for the fingerlever;

"To reinforce the action of linger lever 37 a spring l? may be provided on the rod 31 as shown, or between the integral head of rod 31 and left ledge 25, as at 48. A; collar 4C9 prevents the paper finger 30 at the right The bow spring members are ar-- claim curvilinear edge 41 of regular form to serve as a guiding edge for a pencil, pen or; stylus inthewriting of slurs and the like, and at the left hand end; with an irregular curve-d edge 4:4 to facilitate the writingofbraces to.

connect staffs. The templet also has portions stamped therefrom to provide interior regular curved edges l3, a l and an irregular curved edge 45. The templet is also arrangedw'ith a straight line 46' extending longitudinally and substantially centrally thereof whereby to plet', with the staff lines on the Writing sheet to facilitate the inarking or writing of angular lines. dinal edges is provided with graduated sectional representation of spaces, bars and forms of music notation. In use the tern plet is pl'aced'over the paper'on the paper shelf after "the mechanically written in usic notation has been impressed thereon toinark on -the sheet slurs and' the like to tie or corn nect suchmusic notes. as it is desired; By the arrangement of the fingers 30 carrying the rollers 29 the writing sheet is held flat and firmly against thetable permitting of the temp'let to be used effectively as a tracing instrumentin conjunction with pencil, pen or stylus. I
